HIGH-PRESSURE PIPE 2

1.Use a refrigerant collecting equipment (for HFC‐134a) to discharge the refrigerant.

2.Remove engine cover. Refer to Exploded View.

3.Remove air cleaner case (bank 2) and air duct (bank 2). Refer to Exploded View.

4.Remove cowl top cover. Refer to Exploded View.

5.Remove air pump hose. Refer to Exploded View (GT-R certified NISSAN dealer).

6.Remove mounting bolt (A) from low‐pressure flexible hose bracket.

7.Remove mounting bolt (B), and then disconnect low‐pressure flexible hose (1) from low‐pressure pipe 2.
■ CAUTION ■
Cap or wrap the joint of the cooler piping with suitable material such as vinyl tape to avoid the entry of air.

8.Disconnect vacuum hose from balance tube.

9.Disconnect one-touch joint between low‐pressure flexible hose (1) and low-pressure pipe 1 with disconnector (A) (SST: 9253089916).


■ CAUTION ■
Cap or wrap the joint of the cooler piping with suitable material such as vinyl tape to avoid the entry of air.

10.Disconnect one-touch joint between high‐pressure pipe 2 (2) and high‐pressure pipe 3 with disconnector (A) (SST: 9253089908).
■ CAUTION ■
Cap or wrap the joint of the cooler piping with suitable material such as vinyl tape to avoid the entry of air.

11.Low ‐pressure flexible hose (1) a position without the hindrance for work.

12.Disconnect one-touch joint between high‐pressure pipe 2 (2) and high‐pressure pipe 1 with disconnector (A) (SST: 9253089908).

13.Remove high-pressure pipe 2 from vehicle clip (B), and then remove high-pressure pipe 2.

Installation is basically the reverse order of removal.

■ CAUTION ■

• Replace O‐rings with new ones. Then apply compressor oil to them when installing.
  
• Female‐side piping connection is thin and easy to deform. Slowly insert the male‐side piping straight in axial direction.
  
• Insert piping securely until a click is heard.
  
• After piping connection is completed, pull male‐side piping by hand to make sure that connection does not come loose.
  
• Check for leakages when recharging refrigerant.
